Question

the following set of data represents the GPA of Math students 0.2,0.5,1.4,1.7,2.1,2.5,3.0,.3.3,3.6,3.7what is the mean,mode,median,and range?

Answer 1

0. Mean = 2.2

,

1. Mode= Multimodal

,

2. Median = 2.3

,

3. Range = 3.7

Step-by-step explanation:

The data is given below:

`0.2,0.5,1.4,1.7,2.1,2.5,3.0,.3.3,3.6,3.7`

(a)Mean.

`\begin{gathered} \text{Mean}=(0.2+0.5+1.4+1.7+2.1+2.5+3.0+3.3+3.6+3.7)/(10) \\ =(22)/(10) \\ =2.2 \end{gathered}`

(b)Mode

The mode is the GPA that appears most. In this case, they all appear once. Therefore, the data set is said to be multimodal.

(c)Median

The median is the term in the middle.

In this case, there are two numbers: 2.1 and 2.5

Therefore, we find the average.

`(2.1+2.5)/(2)=(4.6)/(2)=2.3`

The median is 2.3

(d)Range

Range = Highest Value - Lowest Value

=3.7 - 0.2

=3.5
